In response to the U.S. EPA SNAP “De-listing” rule and in support of the North American Amendment to the Montreal Protocol, Natural Resources Canada (NRCan) has released a proposed rule to gradually reduce HFC use in Canada over the next 20 years, and to disallow the use of specific HFCs for some applications that are important to the HVAC&R industry on a shorter term schedule. This presentation will provide a summary of the proposed rule, examine the implications to certain product sectors and to the availability of refrigerants in the market place, and make comparisons to other HFC reduction schemes.
